Quantum sensors: Which ones are the most promising?

17 January 2018

Quantum sensors of the new generation are still at the development stage in leading laboratories of the world. Such sensors are likely to be in demand in many industries in the future: at least in oil and gas, transport and construction.

Hypersensitive properties at microscopic sizes is the main feature of quantum sensors. We can name some most promising sensors.

The development of MRI molecules is necessary in medicine. For example, doctors are studying the human body at the level of organs, quantum sensors will enable the body to be studied at the cellular level.

Such particles can scan proteins. The main task is to detect the affected proteins in the early stages of Creutzfeldt-Jakob disease, or mad cow disease. MRI can not accurately diagnose this disease. Probably, sensors will be able to penetrate into any human cells for diagnosis in the future.

A quantum gravimeter is a sensor that helps to find new deposits of minerals, for example, oil. In addition, devices with a gravimeter can find dangerous for miners emptiness below the surface of earth.

"Cold" atoms is the basis of the sensor: when cooled to almost zero, they become very sensitive to the slightest changes in gravity. As a result, these changes are recorded.

"Quantum film" has a wide dynamic range and high sensitivity to light. In it, light passes through a matrix of colored filters and hits the layer with quantum dots. The special location of elements improves the ability of film to perceive light: images are excellent even in poor lightning.

A quantum clock is an unusual kind of atomic clock. In addition to time, it can measure gravity. The standard for measurement is the Cesium-133 atom, because atoms are "ticking" in such watches. Quantum clock is 37 times more accurate than any other in the world.

Information is an expensive asset. Information leak can deprive money, position in society and even freedom. 650 million rubles were stolen from bank cards of Russians as a result of hacker attacks in 2016. The article 75 of Arbitration Procedure...

A team of scientists from the United States and the Kingdom of the Netherlands managed to combine a pair of one-electron spin qubits into a processor and implement elementary quantum algorithms using it. Quantum dots were the basis for qubits....
